Abstract (en)
[origin: EP0304810A1] A silver halide color photographic material composed of a support having thereon at least one light-sensitive silver halide emulsion layer, at least one layer thereof containing a yellow coupler represented by formula (I), a sparingly water-soluble epoxy compound represented by formula (II) and a water-insoluble but organic solvent-soluble homopolymer or copolymer: <CHEM> wherein R11 represents an N-arylcarbamoyl group; and Z11 represents a group capable of being released by a reaction with the oxidation product of an aromatic primary amine color developing agent; and <CHEM> wherein R1, R2, R3 and R4, which may be the same or different, each represents hydrogen, an aliphatic group, an aromatic group, an aliphatic oxycarbonyl group, an aromatic oxycarbonyl group or a carbamoyl group; provided that at least one of R1, R2, R3 and R4 represents a group other than hydrogen; R1, R2, R3 and R4 contain a total of 8 to 60 carbon atoms; and R1 and R2, or R1 and R3 may be linked to form a 5-membered to 7-membered ring. Because of the combination of the particular yellow coupler, epoxy resin and polymer, the storage stability of the yellow image formed in the material is excellent.
